Anaphylaxis is an allergic reaction in which serious side effects occur in the body against certain substances.
According to foreign media such as the Daily Mail, Lee Rogers (34), who lives in Durham County, England, suffered toothache, but was unable to make a dental appointment due to a huge atmosphere, and had to receive emergency hospital treatment due to a tooth infection.
Medical staff at North Durham University Hospital have decided to conduct CT scans to investigate tooth abscesses.
Doctors suspected that she may be suffering from Ludwig's angina, a life-threatening bacterial infection caused by a tooth infection.
A contrast medium was administered for examination, and immediately Rogers suffered a fatal anaphylactic shock.
Medical staff urgently performed CPR, but about an hour and a half after the contrast medium was administered, she died.
Her mother, Pam Rogers, claimed that the hospital did not adequately explain to her daughter the risks of CT scans.
She `doesn't accept that the hospital staff have been too busy' and"they just handed out papers explaining the risks", he pointed out.
She added: "I want to let others know the dangers of contrast media and the problems with the UK health service," he added.
On the other hand, contrast agents are drugs that are administered to the human body to increase or lower the transmittance of X-rays during imaging diagnostic tests and procedures so that tissues and blood vessels can be seen clearly.
Injectable contrast agents include CT and MRI contrast agents.
Iodized contrast agents are mainly used for CT examination and gadolinium contrast agents are mainly used for MRI examination.
According to the Ministry of Food and Drug Safety's analysis of the risk of adverse drug reactions in seven hospitals in Korea in the past, the incidence of adverse drug reactions in contrast media was very low at 0.72%. However, if there are various risk factors, the incidence rate increases rapidly.
Patients who experienced adverse reactions after using contrast agents in the past had a 68 times higher risk of side effects reoccurring. The risk of side effects was 14 times higher even when a family member experienced adverse reactions. It was seven times higher in the case of allergic diseases.
Accordingly, before undergoing angiography, medical staff must be informed of their past experience of adverse reactions to contrast media, family history, and medical history. It should also be told whether you are taking medication or not.
